The Series 6565 Straight Steel Female JIC Swivel x Female JIC Swivel adapters are hydraulic fittings designed for fluid power systems, featuring two female JIC (Joint Industry Council) 37° flare connections. These adapters are made of durable materials such as carbon or stainless steel, providing reliable, leak-free performance in high-temperature applications where O-rings are unsuitable. JIC fittings are known for their mechanical sealing design, where the male flared and female coned seats create a secure connection without deformation, allowing for repeated disconnection and reconnection. While they are widely used, they have a lower pressure rating than some other fittings and are prone to flare damage if over-tightened. These fittings are easily interchangeable with other SAE fittings, offering versatility in size, material, and application.
